Number Investigations

This collection of investigational activities explore numbers in a variety of contexts.  They are particularly good for challenging high-attaining primary children.

Polygonals

Age 7 to 11
Challenge Level Yellow starYellow starYellow star

Polygonal numbers are those that are arranged in shapes as they enlarge. Explore the polygonal numbers drawn here.

Consecutive Numbers

Age 7 to 14
Challenge Level Yellow star

An investigation involving adding and subtracting sets of consecutive numbers. Lots to find out, lots to explore.

Number Pattern Explorations

Age 7 to 14
Challenge Level Yellow starYellow star

Investigate what happens if we create number patterns using some simple rules.

So It's Times!

Age 7 to 14

How will you decide which way of flipping over and/or turning the grid will give you the highest total?

Steps to the Podium

Age 7 to 14
